Question

the charge of an electron is 1.6x10^-19 coulombs what will be the value charge on Na+

Answer 1

same as on 1 charge(1.6 × 10^-19) as Sodium has only single charge on it!!

Answer 2

Explanation:

Charɡe = ne , where n = number of electrons and e =electrons

q = ne

Now , number of electrons present in Na =11

So number of electrons in Na+=11−1=10 ( Na+ means Na has lossed a electron)

now , q=10×1.6×10-¹⁹

q=1.6× 10-¹⁸
